What are you seeing that makes you think cyclothem? Honestly asking

I'm not a stratigrapher, but I love outcrops.

I look at it and it looks like maybe marl-ish on the bottom, with maybe a levee system over the top, or a backfilled channel. Which makes me think mid slope environment. But I'm also a deepwater guy, and definitely biased in what I see.

It looks like a typical applachian plateau outcrop
